* Nikola Tesla: Promoted alternating current (AC).
* Thomas Edison: Promoted direct current (DC).
Here's why their choices differed:
* Tesla's AC: AC has several advantages over DC for long-distance power transmission. It can be easily transformed to higher voltages for efficient transmission and then back down to safe levels for use. This made AC ideal for building large-scale power grids.
* Edison's DC: DC was the initial technology, and Edison had invested heavily in its infrastructure. He believed DC was safer and more reliable, especially for the limited range of use at the time.
The "War of Currents"
The rivalry between Tesla and Edison, known as the "War of Currents," involved a fierce public debate about the merits of each system. Edison even conducted a smear campaign against AC, highlighting its dangers (which were real but could be mitigated with safety precautions).
Ultimately, AC won the "war," becoming the standard for electrical power systems worldwide due to its advantages for long-distance transmission.
Interesting Fact: While AC is now the dominant form of power transmission, DC is experiencing a resurgence in some areas. This is due to advancements in high-voltage direct current (HVDC) technology for long-distance transmission and the growing use of DC power in electric vehicles and renewable energy systems.
